Currently, we run into a number of WARN()s when attempting to unload the amdgpu driver (e.g. using "modprobe -r amdgpu"). These all stem from calling drm_encoder_cleanup() too early. So, to fix this we can stop calling drm_encoder_cleanup() from amdgpu_dm_fini() and instead have it be called from amdgpu_dm_encoder_destroy(). Also, we don't need to free in amdgpu_dm_encoder_destroy() since mst_encoders[] isn't explicitly allocated by the slab allocator. Fixes: f74367e4 ("drm/amdgpu/display: create fake mst encoders ahead of time (v4)") Reviewed-by:

The YCC conversion matrix for RGB -> COLOR_SPACE_YCBCR2020_TYPE is missing the values for the fourth column of the matrix. The fourth column of the matrix is essentially just a value that is added given that the color is 3 components in size. These values are needed to bias the chroma from the [-1, 1] -> [0, 1] range. This fixes color being very green when using Gamescope HDR on HDMI output which prefers YCC 4:4:4. Fixes: 40df2f80 ("drm/amd/display: color space ycbcr709 support") Reviewed-by:

We are observing performance drop in many usecases which include games, 3D benchmark applications,etc.. To solve this problem, We are strictly not allowing top down flag enabled allocations to steal the memory space from cpu visible region. The idea is, we are sorting each order list entries in ascending order and compare the last entry of each order list in the freelist and return the max block. This patch improves the 3D benchmark scores and solves fragmentation issues. All drm buddy selftests are verfied. drm_buddy: pass:6 fail:0 skip:0 total:6 Signed-off-by:

After applying an engine reset, on some platforms like Jasperlake, we occasionally detect that the engine state is not cleared until shortly after the resume. As we try to resume the engine with volatile internal state, the first request fails with a spurious CS event (it looks like it reports a lite-restore to the hung context, instead of the expected idle->active context switch).

User resource lookups used rcu to avoid two extra atomics. Unfortunately the rcu paths were buggy and it was easy to make the driver crash by submitting command buffers from two different threads. Because the lookups never show up in performance profiles replace them with a regular spin lock which fixes the races in accesses to those shared resources. Fixes kernel oops'es in IGT's vmwgfx execution_buffer stress test and seen crashes with apps using shared resources.

TPM 1 is sometimes broken across system suspends, due to races or locking issues or something else that haven't been diagnosed or fixed yet, most likely having to do with concurrent reads from the TPM's hardware random number generator driver. These issues prevent the system from actually suspending, with errors like: tpm tpm0: A TPM error (28) occurred continue selftest ... tpm tpm0: A TPM error (28) occurred attempting get random ... tpm tpm0: Error (28) sending savestate before suspend tpm_tis 00:08: PM: __pnp_bus_suspend(): tpm_pm_suspend+0x0/0x80 returns 28 tpm_tis 00:08: PM: dpm_run_callback(): pnp_bus_suspend+0x0/0x10 returns 28 tpm_tis 00:08: PM: failed to suspend: error 28 PM: Some devices failed to suspend, or early wake event detected This issue was partially fixed by 23393c64 ("char: tpm: Protect tpm_pm_suspend with locks"), in a last minute 6.1 commit that Linus took directly because the TPM maintainers weren't available. However, it seems like this just addresses the most common cases of the bug, rather than addressing it entirely. So there are more things to fix still, apparently. In lieu of actually fixing the underlying bug, just allow system suspend to continue, so that laptops still go to sleep fine. Later, this can be reverted when the real bug is fixed.

Commit 55d1cbbb ("hfs/hfsplus: use WARN_ON for sanity check") fixed a build warning by turning a comment into a WARN_ON(), but it turns out that syzbot then complains because it can trigger said warning with a corrupted hfs image. The warning actually does warn about a bad situation, but we are much better off just handling it as the error it is. So rather than warn about us doing bad things, stop doing the bad things and return -EIO. While at it, also fix a memory leak that was introduced by an earlier fix for a similar syzbot warning situation, and add a check for one case that historically wasn't handled at all (ie neither comment nor subsequent WARN_ON).

Pull block fixes from Jens Axboe: "The big change here is obviously the revert of the pktcdvd driver removal. Outside of that, just minor tweaks. In detail: - Re-instate the pktcdvd driver, which necessitates adding back bio_copy_data_iter() and the fops->devnode() hook for now (me) - Fix for splitting of a bio marked as NOWAIT, causing either nowait reads or writes to error with EAGAIN even if parts of the IO completed (me) - Fix for ublk, punting management commands to io-wq as they can all easily block for extended periods of time (Ming) - Removal of SRCU dependency for the block layer (Paul)" * tag 'block-2023-01-06' of git://git.kernel.dk/linux: block: Remove "select SRCU" Revert "pktcdvd: remove driver." Revert "block: remove devnode callback from struct block_device_operations" Revert "block: bio_copy_data_iter" ublk: honor IO_URING_F_NONBLOCK for handling control command block: don't allow splitting of a REQ_NOWAIT bio block: handle bio_split_to_limits() NULL return
